Display end date of multi-day events

Hello everyone,

One of my clients use JEvents on his website to display some events. Now he wants to display the end date from multi-day events after the start date of the event. At the moment im using a custom layout to display/style the events in the events list.
I want to display the date of single-day events like this: 01/26/2019
The date of multi-day events should look like this: 01/26/2019 - 01/28/2019

How can I do this in JEvents? I'm asking because I don't have as much experience to do this ;-)

Thanks for your help!
